"It is a lot of rain, especially in the winter season. Some of it may be absorbed by the snow pack. But definitely we're expecting some accumulation of rain causing some problems; more melting and flooding potential," she said.

"There will be significant areas of the region within the City of Windsor and the entire County of Essex that will be impacted on by standing water that may in places exceed .30 cm," the authority said in a media release. "Due to roadside drains, ditches and other drainage facilities being filled with snow and ice there is a high probability of flooding over road surfaces at many locations throughout the region."

ERCA said standing water depths may be "very deep and are potentially extremely hazardous."

"People, pets and livestock should be kept away from areas of standing water," the authority said.
